| 520 | |a"The Canadian Wildlife Service has been monitoring a wide variety of chemical contaminants in wildlife. This monitoring has been ongoing for several years, and is primarily from aquatic ecosystems. Recent interest in pesticides and other contaminants in terrestrial ecosystems has prompted a search for one or more appropriate monitor species. Bird species which breed in nest boxes are relatively easy to study and manipulate. They also lend themselves well to volunteer participation. In addition, several such species are distributed widely throughout the province. This paper summarizes known bluebird trail activity in Ontario. It presents details of a 1987 survey of bluebird utilization of nest-box trails in Ontario. Finally, the paper assesses the feasibility of using bluebird trails to assist in monitoring the effects of agricultural chemicals on natural-components of agriculturally-modified ecosystems in Ontario"--Introd., p. 4-5. |
